SIGNAL-BOMB.

SPECIFICATION forming part of Letters Patent No. 399,854, dated March19, 1889.

Application filed October 1'7, 1388. Serial No. 288,312. (No model.)

object of the invention being to provide a signal-bomb which will not beaffected by dampness, which maybe ignited irrespective of the state ofthe weather, and which shall be so constructed that in exploding it willsend aloft a heavy volume of flame and smoke, an explosive giving aheavy detonation being preferably employed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the views.

Figure 1 is a central sectional elevation of my improved signaling-bomb.Fig. 2 is a central sectional elevation of a modified construction. Fig.3 is a plan view of the construction shown in Fig. 1, the top disk orplate, however, being removed. Fig. i is a sectional plan view taken online x w of Fig. 2. Fig. 5 is a side view of the screw-cap, and Fig. 6is an end view of said cap.

In constructing such a bomb as the one forming the subject-matter ofthis application, I provide an outer vessel, 10, which is preferablycylindrical, but which might be made of any desired form. \Vithin thevessel 10 there is placed a vessel, 11, which rests upon the bottom ofthe vessel 10, and in connection with the vessel 11, I arrange tubes 12and 13, said tubes extending through a disk, 14:, which is tightlyconnected to the vessel 10, thus forming an air and water tightcompartment, A. The tube 12 extends downward within the vessel 11, thewalls of this extending section of the tube being perforated, as shownat a. Above the disk 14 there is arranged a-removable disk, 15, formedwith an'upwardly-extending and threaded nipple, 16, which nipple servesas the support for the fuse 17, this fuse being carried downward withinthe tube 12, as is clearly shown in Fig. 1.

In preparing the bomb for use the vessel 11 is filled with any properexplosive, the material being introduced through the tube 13. After thevessel 11 has been filled with the explosive, a small amount of theexplosive is introduced through the tube 12, the lower end of the fuse17 resting upon the explosive so placed within the tube 12. To the upperend of the fuse there is attached an instantaneous fuseigniter, Z),which extends slightly above the upper end of the nipple 16. After thefuse has been properly prepared and placed, the nipple 16 is covered bya cap, 20, that is internally threaded to engage the thread of thenipple. In the outer face of the cap 20 there are formed one or moreconcave grooves, c, the exposed face of the cap within these groovesbeing roughened. Such, in short, is my improved form of bomb.

In using the bomb, the cap 20 is removed and any one of its roughenedfaces is drawn against the igniter above the upper end of the fuse. Thebomb is then thrown overboard, and upon striking the water will floatand as sume a position that is substantially vertical, care being takenin the filling of the bomb to secure sufficient weight within or belowthe vessel 1.1 to hold the vessel 10 in a vertical position. \Vhen theexplosion takes place, the water in which the bomb is immersed acts as aconfining medium, and the products of combustion will rise vertically toa great height, so that they may be seen for many miles around.

In selecting the explosive it is desirable that an explosive which willproduce a heavy smoke and a great noise be employed. In certain cases itmight be well to provide the bomb above described with a rocket, and tothis end I would in some cases attach a cup, 23,-to the vessel 11, thetubes 12 and 13 being in this case removed to one side, as shown in Fig.4. The cup 23 serves as the support for the lower end of a rocket, 30,the upper end of the rocket being held by a disk, 01, that is arrangedbelow the disk 14, the disk o1 being centrally apertured to prox ide forthe passage of the rocket, as is clearly shown in Fig. 2. Vith thisconstruction the rocket would be ignited by the explosive within thevessel 1.1.

The advantages of such a bomb as the one above described are great andvaried, inasmuch as the signal is of a nature such that it would beunderstood by persons of every 11ationality, and the construction of thebomb is such that it might be used where other signaling appliancescould not be employed.

Having thus described my invention, I claim as new and desire to secureby LettersPatent 1. A signal-bomb formed with an air-chamber, a chamberadapted to receive an explosive material and provided with a tube whichleads from the explosive-receiving chamber through the air-chamber, saidtube being adapted to receive a fuse, a disk arranged above the upperend of the tube, a nipple extending upward from the disk, and a capformed with a roughened surface adapted to fit upon the nipple,substantially as described.

2. In a bomb, the combination, with a vessel, 10, of a vessel,11,arranged therein, adisk, 11, also arranged within the vessel 10 andabove the vessel 11, tubes 12 and 13, leading from" the vessel 11 upwardthrough the vessel 10 and through the disk 14, a disk, 15, arrangedabove the disk 14, a nipple formed upon said disk, and a roughened-facedcap arranged in connection with the nipple, substantially as described.

3. 'In a bomb, the combination, with a vessel formed with an air-chamberand provided with a chamber adapted to receive an explosive below saidairs-chamber, of a rocket arranged within the air-chamber and a fusetubeleading downward through the air-chamber to the explosive-chamber,substantially as described.

4. The combination, with a vessel provided with a nipple into which thefuse is adapted to project, of a cap fitting on the nipple and having aroughened surface, substantially as and for the purpose set forth.
